Motor Winding Fiber Optic Temperature Probe
Direct optical point measurement inside motors, generators and other high-EMI rotating electrical machines.
ROTATING MACHINE WINDING PROBE
Measure Winding Temperature Without an Electrical Sensor Signal
The compact fluorescent sensing tip is positioned at a selected winding location while the optical fiber carries the response to a compatible instrument outside the measurement point.
Probe placement, fixing, lead exit and mechanical protection must be designed around the machine. The product is a passive point probe rather than a complete motor monitoring system.
- Motor and generator winding use
- -40 °C to +260 °C configurable range
- 2.5 or 3 mm diameter
- Optical immunity to EMI
Product Overview
The motor winding fiber optic temperature probe is a passive optical component for direct measurement at a selected winding location in motors, generators and related electrical machines. It is intended to bring the sensing point close to the thermal area being assessed rather than infer winding temperature from an external surface.
The final probe location, lead exit and host channel arrangement should be reviewed with the machine design. A compatible fluorescence transmitter or monitoring host is needed to turn the optical response into temperature data and any required alarm or communication output.
MACHINE THERMAL POINT
Selecting a Representative Winding Point
The selected point should correspond to the part of the winding that the project needs to understand or protect.
- Define the winding location before production or rebuild work.
- Use direct point measurement where external measurements are insufficient.
- Plan channel count around the number of required winding points.
ROUTING REVIEW
Planning Lead Exit and Mechanical Protection
The optical route needs to remain practical through the machine structure and into the compatible instrument.
- Confirm the available exit route.
- Avoid mechanical pinch points and unapplication-specific bends.
- Coordinate probe geometry with winding construction.
SHARED MEASUREMENT PRINCIPLE
Passive Point Sensing With a Compatible Instrument
The fluorescent sensing tip measures one selected point. A compatible instrument supplies the optical excitation, processes the returned signal and provides the temperature output. See the standard fluorescence probe for the full measurement principle.
PRODUCT CONSTRUCTION
Motor Winding Probe and Lead-Exit Construction
The product is selected around the winding point, the lead exit and the mechanical path from the machine to the compatible instrument.
Winding sensing point
The fluorescent tip is placed at the selected motor or generator winding location.
Compact optical lead
The optical route is planned through the machine without carrying an electrical temperature signal at the sensing point.
Lead-exit connection
The fiber is brought to the compatible instrument through the approved machine exit path.

BUYER QUESTIONS
Frequently Asked Questions
Can this probe measure a complete motor winding?
It measures one defined point per probe. Multiple probes and channels are used for multiple winding locations.
Does EMI affect the optical signal?
The optical transmission path is immune to electromagnetic pickup, although the complete installation still requires engineering review.
Can the probe be embedded during winding manufacture?
Embedding and fixing depend on the machine design and should be coordinated with the motor or generator manufacturer.
Does it include alarms or communication?
No. Alarm, RS485 or other outputs are functions of the selected monitoring instrument.
What dimensions are available?
The collected data lists 2.5 mm or 3 mm configurations. Final geometry should be confirmed for the winding space.
What information is needed for selection?
Provide the machine type, winding location, temperature range, lead route, number of points and instrument interface requirements.
